I believe that band was called "Black Sabbath", but I could be wrong. Hmm, lemme go check the CD covers............funny, says "Black Sabbath." Hmm, how about my vinyl copies...........hey hey hey whadya know, "Black Sabbath." They've even got it inside the booklets, and on the CD itself, and on the back cover, and on the inner sleeve, and on the LP, yeah, strange.
